The BADI Implementation "ISU_C4C_V2_TECH_OBJS_REPL" is not active. This report will use the BADI to determine the receiver system(Service Cloud V2 system id) and append it into the outgoing messages. 

If the id is missing, Service Cloud will reject the messages and send the above error back to CPI - then the CPI MPL ID will be sent back to ISU with status 500.

Implement the BADI "ISU_C4C_V2_TECH_OBJS_REPL" >> RECEIVER_ADJUST_DATA. 

Use the statement APPEND 'sap_cloud_crm_my123456' TO ct_receiver_system in the BADI.

The Service Cloud V2 system id "sap_cloud_crm_my123456" can be found in the Settings >> Communication Systems >> Find the system ID with description "Default communication"
